Informatica aplicada a la comprensión textual     

Luis Guerra  Juan Martín 《Cultura y Educación》2013,25(13):95-99

Uno de los inconvenientes de los programas didácticos que tratan de desarrollar en el alumno estrategias de comprensión lectora es que, dada la estructura grupal de la clase, deben aplicarse colectivamente cuando su propia naturaleza requeriría la aplicación individual. El ordenador puede conseguir aplicar a toda una clase los mismos modelos de comprensión, pero individualizadamente. En este artículo se expone un modelo experimental.  相似文献

Determinants of cultural and popular celebration attendance: the case study of Seville Spring Fiestas     

María Luisa Palma  Luis Palma  Luis Fernando Aguado 《Journal of Cultural Economics》2013,37(1):87-107

The Spring Fiestas in Seville (Spain) (SFS) are the most important cultural events in the city each year. The present paper pursues two aims. The first is to characterize the SFS as a new prototype of a complex cultural good that expresses the link between the people and the place in which they live based on material and immaterial cultural heritage represented through popular celebrations. The second goal is to conduct an empirical analysis of the determinants that shape attendance intensity by estimating a zero-truncated count data model using a unique dataset of attendees at the SFS in 2009. Findings indicate that attendance is strongly associated with variables reflecting knowledge, institutional links, past experiences, and the perceived external benefits generated by the existence of the SFS. The article contributes to the literature by exploring participation in popular celebrations, a field of inquiry that to date is extremely limited in cultural economics.  相似文献   

Sensemaking and social processes in digital government projects     

Luis Felipe Luna-Reyes  David F. Andersen  Laura J. Black  Theresa A. Pardo 《Government Information Quarterly》2021,38(2):101570

This research identifies main feedback dynamics associated with social processes necessary to make sense of ambiguous project goals, typical of large digital government projects. The study reports on findings from a case analysis using participatory approaches in system dynamics, based on a digital government project integrating information systems of New York's criminal justice agencies. Findings stress the importance of visuals in the sensemaking process that results from the interaction of technical and social outcomes produced through identifying and continuously re-interpreting main project issues and goals. Project analyses suggest that requisite elements of successfully managing this type of project include 1) facilitation that enables diversity of ideas, 2) shared visuals and re-presentations of participants' efforts to work on the issues, and 3) iterative social construction of objectives, progress, and valid processes for doing the work; each of these plays a role in three different feedback processes sustaining (or undermining) the group engagement needed to yield successful integrative work. The study contributes to the literature in digital government by introducing the lenses of people-centered project management processes, an emerging approach in project management, to underscore the role of social processes in technical projects.  相似文献   

Power training in elite young soccer players: Effects of using loads above or below the optimum power zone     

Irineu Loturco  Lucas A. Pereira  Valter P. Reis  Chris Bishop  Vinicius Zanetti  Pedro E. Alcaraz 《Journal of sports sciences》2020,38(11-12):1416-1422

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献   

Correlation analysis of performance measures for multi-label classification     

Rafael B. Pereira  Alexandre Plastino  Bianca Zadrozny  Luiz H.C. Merschmann 《Information processing & management》2018,54(3):359-369

In many important application domains, such as text categorization, scene classification, biomolecular analysis and medical diagnosis, examples are naturally associated with more than one class label, giving rise to multi-label classification problems. This fact has led, in recent years, to a substantial amount of research in multi-label classification. In order to evaluate and compare multi-label classifiers, researchers have adapted evaluation measures from the single-label paradigm, like Precision and Recall; and also have developed many different measures specifically for the multi-label paradigm, like Hamming Loss and Subset Accuracy. However, these evaluation measures have been used arbitrarily in multi-label classification experiments, without an objective analysis of correlation or bias. This can lead to misleading conclusions, as the experimental results may appear to favor a specific behavior depending on the subset of measures chosen. Also, as different papers in the area currently employ distinct subsets of measures, it is difficult to compare results across papers. In this work, we provide a thorough analysis of multi-label evaluation measures, and we give concrete suggestions for researchers to make an informed decision when choosing evaluation measures for multi-label classification.  相似文献   

Initial Validity and Reliability of the Portuguese Borg Rating of Perceived Exertion 6-20 Scale     

Luana L. Cabral  Fábio Y. Nakamura  Joice M. F. Stefanello  Luiz C. V. Pessoa  Bruno P. C. Smirmaul  Gleber Pereira 《Measurement in physical education and exercise science》2020,24(2):103-114

ABSTRACT

The aims of this study were to perform the cross-cultural adaptation of the Borg Rating of Perceived Exertion (RPE) 6–20 Scale to Brazilian Portuguese language and to start testing its validity and reliability. After performing the cross-cultural adaptation of the Scale, concurrent and discriminative validity, and reliability were determined on a treadmill in young (18–30 years) and older adult women (60–75 years). Considering young and older adult women, RPE presented high and moderate positive correlation with heart rate and high and low positive correlation with oxygen consumption, respectively. Older adult women presented RPE (11 ± 2) significantly higher than young ones (8 ± 1) exercising at the same absolute intensity. Intraclass coefficient correlation was excellent for RPE to young and older adult women. The Scale presented concurrent validity only to young adult women, whereas it presented discriminative validity between such groups of women. Moreover, the scale is reliable to young and older adult women.  相似文献   

Non‐at‐risk adolescents' attitudes towards reading in a Singapore secondary school     

Wendy Bokhorst‐Heng  Delfin Pereira 《Journal of Research in Reading》2008,31(3):285-301

In this paper, we examine the various nuanced dimensions of adolescents' dispositions towards reading in one secondary school in Singapore, where a high‐stakes examination culture often threatens to colonise the practices of leisure reading. Our focus is on the better and more avid readers as they were the ones that developed the more negative attitudes towards reading at the end of their first year in secondary school. Our analysis found that there were no significant differences between boys and girls in their declining attitudes, and that for both ‘intrinsic motivation’ saw the greatest decline. However, attitudes related to learning orientation remained stable, suggesting both the impact of constraints in an exam‐oriented educational structure as well as possibilities for developing reading pedagogy and adolescent reading programmes. We argue that the more educators are aware of the multidimensionality and complexity of the attitudes and values that students bring to their reading, the more effectively they will be able to design and implement programmes and pedagogy to foster positive attitudes and promote a lifelong love for reading.  相似文献
